Prior to that he was the founder and director of the Rubin Institute for Advanced Orthopedics,director of the International Center for Limb Lengthening (ICLL) at Sinai Hospital of Baltimore andChief of Pediatric Orthopedics at the University of Maryland in Baltimore.

Dr. Dror Paley –introduction

He internationally recognized for his expertise in limb lengthening and reconstruction.

Trained under the guidance of Professor Ilizarov of Russia (Ilizarov method) and organized the first Ilizarov course in the US, andunder the guidance of Professor Debastiani of Italy (Orthofix method). In 1986, he introduced the Ilizarov method in the United States and Canada. Since that time, he has performed more than 17,000 limb lengthening and reconstruction-related procedures.
Patients come to him from all over the US and from more than 80 countries over six continents.

He is the current president-elect of the International Limb Lengthening and Reconstruction Society and the Chairman of the Combined Meeting of ILLRS, LLRS and ASAMI International-BR. He has lectured and demonstrated surgery in more than 50 countries and provides training for specialists from around the world through a fellowship program.

Dr. Paley is known as the most experienced surgeon in the world in limb lengthening and deformity correction.

Delivering Innovative Solutions:

Dr Paley has developed more than 100 new operative procedures for bone and soft tissue reconstruction of congenital, developmental and post-traumatic limb disorders, such as: superhip procedure, superknee procedure, superankle procedure, ulnarization, percutaneous Gigli saw osteotomy, focal dome osteotomy, angulation-translation osteotomy, etc.

His new methods to lengthen and/or straighten deformed bones and to reconstruct congenital short limbs (LRS) avoid amputation, a frequently recommended alternative.
The results of LRS for conditions such as fibular hemimelia, tibial hemimelia and congenital femoral deficiency have given children who would have otherwise lost their legs, excellent function without the need for a prosthesis. Furthermore, the methods used to classify these conditions now bear his name.

Dr Paley has also discovered a new, simple, but accurate method for prediction of leg length discrepancy and height at skeletal maturity – The Multiplier method, His method for using a combination of an intramedullary rod and an external fixator (LON and FAN of deformities) has shortened the treatment time required.

Dr. Paley was the first US surgeon to implant the PRECICE 1 device in the US and is the surgeon inventor of the PRECICE 2.

Perhaps his most noteworthy contribution to medicine is the science of limb deformity correction, sometimes referred to as “deformity theory.” This is published in his textbook, “Principles of Deformity Correction” which is considered the ‘bible’ of deformity correction surgery. This book has been reprinted 4 times and is considered an orthopedic best-seller and classic.

Treatment for Special Orthopedic Conditions:

Dr Paley’s expertise extends equally to children and adults, as well as for the upper and lower extremities. He specializes in the diagnosis and treatment of:

  • Congenital lower limb deformities.
  • Hemihypertrophy, fibular hemimelia, tibial hemimelia, posteromedial tibial bow, congenital dislocation of patella, congenital pterygium of knee, congenital pseudarthrosis.
  • Congenital upper limb deformities of all kind.
  • Other upper and lower limb deformities due to: growth arrest, fractures, radiation, infection.
  • Post-traumatic limb deformities and leg length discrepancies (e.g., malunion)
  • Bone healing problems (e.g., problem fractures, delayed union, nonunion, congenital pseudoarthrosis)
  • Bone defects, bone and joint infections (e.g., osteomyelitis, septic arthritis, sequellae of neonatal sepsis)
  • Skeletal dysplasias (e.g., achondroplasia, hypochondroplasia, spondyloepiphyseal dysplasia, pseudoachondroplasia, chondrometaphysealdypslasia, mesomelic dysplasia, Ellis-van
  • Creveld, melorheostosis, diastrophic dwarfism
  • Tumor-like conditions (e.g., fibrous dysplasia, neurofibromatosis, multiple hereditary exostoses (MHE), Ollier’s disease)
  • Metabolic disorders (e.g., rickets, Paget’s disease, osteogenesis imperfecta, osteopetrosis, osteoporosis)
  • Other miscellaneous developmental deformities (e.g., Blount’s disease, growth arrest, neonatal sepsis sequelae)
  • Joint contractures and joint stiffness (e.g: Chondrolysis, hip-knee-ankle arthritis)
  • Foot deformities (e.g., clubfoot, vertical talus, dropfoot, equinus, flatfoot, short metatarsals (brachymetatarsia), Charcot-Marie-Tooth disease)
  • Hip disorders including Perthes, hip dislocation and dysplasia in children and young adults and neonatal septic hip sequellae
  • Short residual limb following amputation
  • Joint preservation for arthritis of the hip, knee and ankle
  • Peripheral nerve disorders (e.g., nerve entrapment)
  • Short stature: normal, constitutional and dwarfism related

Dr. Dror Paley interviewed on Oprah



Limb lengthening and deformity correction is a very complicated process. Meticulous surgical technique, vigilant follow up, and aggressive rehabilitation are required for a successful outcome. The results of lengthening are highly dependent on the experience of the surgeon and his surrounding clinical staff. A more experienced surgeon knows how best to perform the surgery and knows how to prevent and treat complications so that there is no residual problem at the end of treatment.


Dr. Paley has been performing lengthening procedures for over twenty-five years. He has performed thousands of lengthening surgeries and he has advanced the scientific understanding of lengthening and deformity correction multiple times throughout his career. He is currently the most experienced limb lengthening surgeon in the world, having performed over 17,000 lengthening surgeries. The Paley Advanced Limb Lengthening Institute in West Palm Beach, Florida, offers patients the most technologically advanced limb lengthening and deformity correction surgeries available as well as comprehensive care from an experienced team of professionals.


At the Paley Institute we are dedicated to personally guiding each patient through the treatment process. Our staff is committed to meeting each patient’s individual needs before, during and after treatment. From preoperative planning, to the hospital stay, followed by physical therapy and post-operative care, our staff supports patients and their families. No detail is too small.
